Three years ago I had the pleasure of performing as Lane, the butler, in a production of Earnest directed by my eldest daughter, with her sister as one of my fellow actors.

I suspect that the author of the blackbird article was more concerned with drawing a comparison between bird and human behavior in an attention-getting way than he was in drawing an accurate parallel with the central definition of "bunburying." You're right, Fred (and welcome to the forum, by the way), the usage doesn't match the definition, but I imagine that Anu doesn't have many examples to draw from.
